BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented March 10, 1908.

Application filed September 28,` 1906, Serial No. 336,622. Renewed August 19, 1907. Serial No. 309,251.

To all whom it may concern:

Be it known that I, JOHN DICKENs, a citizen of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented new and Auseful Improvements in Bottle-Closures, of which thev following is a specification.

This invention relates to bottle closures and aims to )rovide, in a manner as hereinafter set forth, an expansible stopper adapted to hermetically seal the -throat of the bottle and at the same time to be easily removable without the vemployment of a specially designed tool or stopper-pulling device.

Tlie invention furt ier aims to provide an expansible stopper having a Vlaterally-extending iiange adapted to be seated upon the edge of the bottle neck and a spun body portion, the spinning being such as to provide the body portion with a plurality of annular ribs arranged in parallelism with respect to each other and forming sur lus metal so that when the body portion of t e stopper is ex anded in the throat -of the bottle the meta will readilyT adjust itself to any irregularities or unevenness inthe inner face of the v bottleneck, thereby forming a tight joint,

-means to prevent the outlet of ture.

and, furthermore, the ribs also act as a gas or the entrance of air.-

The invention further aims to provide a bottle closure which shall be extremely simple in its construction, readily removed when occasion so requires, strong, durable, hermetically sealing the throat of the bottle, eflicient in its use, readily expanded to closure position, and inexpensive to manufac- With the view, the invention consists of the novel construction, combination and arran ement of parts hereinafter more speciica ly described and illustrated in the accompanying.

drawings, wherein is shown the preferred embodiment of the inventlon, but 1t 1s to be understood that changes, var1at1ons and modifications can be resorted to which como fore-going and other objects in,

plana'nd Fig. 3 a vertical section of a bottle closure in accordance with this invention. Fig. 4 is a vertical sectional view of a bottle neck showing the position of `the bottle closure before expansion. Fig. 5 is a view in section illustrating the expanded closure withinthe bottle neck. y

Referring to the drawings by reference characters 1 denotes the bottle neck, 2 the throat and 3 thewall of the throat. The wall 3 near the upper end thereof is cut away so as to form a shoulder 4 and that portion of the wall of the throat above the shoulder 4 substantially conoidal. By way of example, that portion of the throat above the shoulder 4 is formed in an irregular manner, as at 4a.

The bottle closure isindicated bythe .reference character, lis Iformed of expansible metal, preferably aluminium, is hollow, open at one end substantially cup-shaped in cross section and is formed at its upper end with a laterally-extending flange 6, which, when s the bottleclosure 5 is in position, is adapted to rest upon the top edge of the bottle neck, as shown 'in Figs. 4 and 5. The body portion of the bottle closure is indicatedby the reference character 7 and is provided with a plurality of annular ribs 8. s un in the said body portion and the said ri s are arranged in parallelism with respect to each other and suitably spaced apart. The providing of the body ortion 7 with the ribs 8 forms sui;- plus meta}l so that when the. said body portion 7 of the closure is expanded in the colloidal-shaped portion of the Wall of the throat of the bottle the metal will readily adjust vitself to any irregularities or unevenness in the wall 3, vthereby forming a tight joint, and, furthermore, the ribs 8 act as a means to revent the outlet of' gas or the entrance oi air when the closure is in sealing position. In this connectionfit will be stated that in some instances parts of the body portion 7 are not expanded because the diameterof that portion 3 of the wall which the body portion 7 engages is such as to not require the smoothing out of the entire body portion, consequently certain of the ribs or certain por-` tions of the ribs remain, and it is these remaining ribs or the portions of the ribs which act to prevent the outlet of gas or the entrance of air. By way of example it will be stated that possibly the gas may get around one rib, but the other rib would prevent the.

.undulated, and the ribs and grooves formed 0n the peri phery'of the body portion 7, as well as the ribs and grooves formed on the inner face ofthe body portion 7, are endless.

When the bottle closure is positioned in the throat of the bottle and expanded it will snugly it the shoulder 4 as shown in Fig. 5, the shoulder 4 acting as a means to prevent the blowing out of the stopper, furthermore, the conoidal-shaped ortion of the Wall 3 of the throat 2 when t e bottle closure is expanded, acts as -a wedge to prevent the blowing out of the closure as the lower portion of the bottle closure when expanded is of a greater diameter than the upper portion. This is caused by the shape of the portion 3? ofthe wall of the throat 2 being substantially conoidal in contour.

The bottle closure is removed by inserting a knife or other suitable instrument between the flange 6 and the edge of the bottle neck and the closure can then be plied off very readily.

What I claim is- 1. A bottle closure having an expansible cup-shaped body portion provided with eircumferentially-extending ribs separated by eircumferentially-extending grooves, the bottom of said body portion adapted to be seated within the neck of a bottle and constituting a closure therefor.

, 2. A bottle closure having an expansible' body portion provided with circumferentially-extending ribs separated by circumferentially-extending grooves, said body portionv terminating at its top in a laterally-ex .tending flange.

3. A metallic bottle closure comprising an expansible cup-shaped body ortion open at its top and having the side tfiereof provided With ribs to form surplus metal so that when the body portion is expanded in the throat of the bottle the metal will readily adjust itself to any irregularities or unevenness in the wall of the throat of the bottle the bottom of said body portion ada ted to be mounted in the hroat of the bott e and form a closure there- A 4. A metallic bottle closure having an expansible body portion provided with ribs to form surplus metal so that whenthe body portion is expanded in the throat of the bottle the metal will readily adjust itself to any irregularities or unevenness in the wall of the throat of the bottle, said body portion terminating at its upper end in a laterally-extending flange. l

5. The combination with a bottle having the Wall of the throat thereof formed with an annular shoulder, of a metallic closure therefor consisting of a substantially cup-shaped member having the bottom thereof seated upon said shoulder and comprising an e.\'- pansible body portion having endless ribs` separated from each other to provide surplus metal when expanding the body portion so that said body portion will readily adjust itself to any irregularities or unevenness in the wall of the throat of the bottle above the shoulder.

6. A metallic closure for bottles consisting of a substantially cup-shaped member comrisinU an ex ansible bod )ortion haviinlr endless ribs separated from each other to provide surplus metal when expanding the body portion so that said body portion will readily adjust itself to any irregularities or unevenness in the wall of the throat of the bottle. said member further comprising a laterallyextending flange at the upper end thereof ada ted to seat upon the edge of the bottle nec when the closure is positioned in the throat of the bottle.

7. The combination with a bottle neck having the wall of the throat thereof provided with a shoulder termina-ting iu a conoidalshaped portion, of aI metallic cup-shaped member mounted on the shoulder in the wall of the throat and comprising an ex ansible. body portion having eireumferentially-extending ribs, said ribs forming surplus metal so that when the body portion of the closure is expanded the metal will readily adjust itself to any irregularities or unevenness in and snugly tit the eonoidal-shalied part of the wall of the throat of the bottle, said member further comprising a laterally-extending flange adapted to be seated upon the edge of the neck of the bottle.

In testimony whereof I have hereunto set GEO. WoLFF, EDWIN L. DECKER..
